UNTTED i STATES PATENT 'Tirion CRIMPING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 237,515, dated February8, 1881.

Application led May 19, 1880. (Model.)

To all whom 'it may concern:

Be it known that I, SAMUEL A. GOULD, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin a Crimping-Machine; and I do hereby declare the following to be afull, clear, and exact description of the invention, that will enableothers skilled in the art to which it appertains to construct and makeuse of the same, reference being had to the accom panying drawings, andto letters and figures of reference marked thereon, forming a part ofthis specification.

This invention relates to improvements in mechanism to be employed incrimping and preparing sheets of zinc to be used as faciugs in themanufacture of wash-boards; and it consists of certain novel features inthe gen,

eral construction, arrangement, and operation of the parts, as will behereinafter more fully explained in detail, and set forth in the claims.

Figure lis an end elevation of my improved crimping-machine Fig. 2, aside elevation of the same; Fig. 3, a vertical longitudinal eentralsection in the plane x x, Fig. l; Fig. 4, a vertical transverse centralsection in the plane y y, Fig. 3; and Fig. 5 shows the `crimpingbed-plate or former detached.

Referring to the drawings, A represents the inclosing and supportingframe-Work. B is a large roller carrying the series of cam-likeprojections C, which are rigidly attached to the periphery of saidroller, and are arranged spirally upon the circumference of the same, asshown in Fig. 2 of the drawings.

The series of tumblcrs 6 are of a rectangular shape, move in a verticalplane, are loosely arranged in their proper working position, and areheld in place by means ot the side bars, 7, as shownin the drawings. Thelower ends ofthese tumblers rest upon the series of cams G, and theperiphery of that portion of the roller B not covered by the camsalternately as the same is rotated, and the tumblers are caused to risein regular succession relative to each other by the contact ofthe seriesof cams, and drop back again onto the roller B, by the force ofgravity,when the cams pass beyond the point of engagement. These seriesof cams do not extend clear around the roller B in a spiral course, buta cylindrical roller B the tumblers are on a level.

bed-plate or former 1l, (shown in Fig. 5 of the surface is left on theperiphery ofthe roller that will permit the series of tumblers to restat the same level at a certain point of revolution-that is, when thelast tumbler is re- 5 leased from contact' with the last cam, the firsttumbler and first cani are about to engage, so at this point ofrevolution of the The upper ends of these tumblers engage with the innerends of the series of bent levers 8, as shown in Fig. 4"of the drawings.These bent levers are loosely arranged in position, the outer endsresting in the recesses 9 in the frame-work A, and the under side of theinner ends resting upon the upper ends of the tnmblers 6. Resting uponthe upper sides of the bent levers 8 are the series of followers 10, theunder sides of which are of the proper shape to conform to the upperbearing-surface ofthe bent levers 8, as shown in Fig. 4 ofthe drawings.The top parts of these followers come in contact with the under side ofthe sheet of zinc and force the same into the recessed drawings,) whichproduces a pattern or design in accordance with the configurationscarved thereon, the upper or impression side of the series of followersbeing always of proper shape to correspond to the configurations in thebed-plate or formery By way of illustration, one design is shown in Fig.5 of the drawings. As many different designs or patterns may be producedas desired by simply removing the bed-plate and followers andsubstituting therefor others of a dierent pattern. Thefollowers aresimply dropped loosely into place; but the bed-plate or former isrigidly attached to the top of the machine by mea-ns of the cross-bars12, which are provided with the notches 13, thereby adapting these partsto securely engage with the ends A of lthe frame-work, and are furthersecured thereto by means of bolts or screws.

The movable frame 14 is placed at one end of the machine and arranged asshown in Fig. 1 of the drawings, and is adapted to move in a verticalplane, and is for the purpose of turning down one edge of the zincfacing ready to be inserted in the wooden back of the Washboard. Theupper cross-piece of the frame 14 is partially cut away to form theshoulder 15,

IOO

(shown in Fig.L 2 of the drawings,) which nips and turns down. one edgeof the zinc facing.

yThe cam 16 (shown in Fig. 1 of the drawings) is attached rigidly to theroller B, near the end, and is placed upon the periphery of the rollerat a point directly opposite the irst ofthe series of cams C, countingfrom the right-hand end oi' the roller. When the roller B is rotatedthis cam 16 is brought in contact with the lower horizontal part of theframe 14 and forces the same downward, thus bringing the shoulder 15 ofthe upper cross-piece of the frame 14 in contact with the edge of thezinc, for the purpose above described. Attached to the upper cross-pieceof the frame 14 is the lower end of the spiral spring 17, the upper endot' this spring being connected to the cleat 18, as shown in Fig. 1 ofthe drawings, and is for the purpose of returning the frame 14 to itsnormal position when the lower end of the frame is released from contactwith the cam 16.

The series otl tumblers, bent levers, and followers are all independentof each other, andr are simply dropped looselyinto their Workin gposition in the machine, and when broken, or any of these parts areunevenly worn, duplicate pieces can be easily and conveniently in-'serted Without causing any unnecessary delay.

The roller B is provided with the shaft 19 and the bearings 20.

The operation of the machine is as follows: When the roller B is causedto rotate, the series oi` cams C are brought in contact with the seriesof' tumblersin regular order of succession, and theseries of bent leversand followers are actuated in the same regular order, thereby graduallyforming the design on the zinc or other material being operated upon. Ifthe pattern were stamped out at one blow, the material would be brokenand torn apart; but by this order of arrangement the sheet of zincgradually receives the impression of the followers, and is thereby drawninward from the loose side and readily adapts itself to the change ofform.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a crimping-machine, the combination, with a former, of the rollerB, provided with the series of cams C, the tumblers 6, the side bars, 7,the bent levers 8, and the followers 10, substantially as herein shownand described.

2. In a crimping-machine, the combination, with the roller B and the cam16, of the vertical moving frame 14, provided with the shoulder 15, thespring 17, and the cleat 18, arranged and operatin g in the manner andfor the purpose set forth.

3. In a crimping-machine, the combination of the roller B, the series ofcams C, the series of tumblers 6, the side bars, 7, the series ofcrooked levers 8, the series of followers 10, and the bed-plate orformer 11, all constructed, arranged, and operating in the manner andfor the purposes herein set forth.
